This battery charges via USB-C with "the Charger", and is not compatible with older Soundboks chargers that are not USB-C.

You spoke. We listened. THE BATTERY's improved performance and new features have been designed from community feedback. We've dropped the recharge time to 2 hours using a 65W charger such as THE CHARGER, made it possible to charge whilst playing your SOUNDBOKS at 11, and designed it to double up as a powerbank.
